Yes, they are the results of water "pooling" for too long a time while
the polymer surface is soft and sensitive. I tend to chase them off
the surface with a hair dryer. The sooner the better.

...if I could just control them, they'd look like either reticulation
or paisley

what manufacturer's plates did you get?

Hi All,

I'm starting to get set up at home to burn photopolymer plates with my
blacklight box built from Dick Sullivan's fabulous directions in his
on PT/PD printing.

What I'm finding is the 80% density, 300lpi screen I'm using to
pre-expose the plate is resulting in a kind of mottling effect. Looks

like water spots directly on the plate.

Has anyone else come across this?
